Marsh is set to launch a new national public sector practice in the New Year.
Marsh said the practice will focus on developing its business with local authorities, development agencies, police and fire authorities across the UK.
The company said the practice will also be able to link into its project risk practice, which manages and delivers risk and insurance programmes relating to PFI/PPP and major outsourcing projects.
The new practice with 'hubs' in Cardiff and Newcastle will be chaired by Julie Page.
Brian Shaw, public sector practice leader at Marsh, said: "The public sector in the UK, particularly at the local level, is undergoing huge change and is extremely active in seeking consultancy and other support to help it modernise and achieve the requirements set by central government.
"Marsh is now exceptionally well placed to respond to its needs."
